- There are at least two missiles (Army/FOG-M, and a Navy project) which use
- some sort
- of spooling mechanism to pay out "cable" (well, probably not more than a
- strand). The Army system is (forgive me pureists) basically a longer range TOW
- anti-tank missile, designed to be launched off a trailer dragged behind a
- Hummer, and will go against either tanks or helos. The Navy missile is more
- interesting because they pay out cable between a fast moving attack plane and
- the missile at up to hmm, at least 20 kilometers; Army system is some number
- not more than 10K.
-
- However, both Army and Navy don't have to worry about rewinding the cable after
- the packages are delivered :-)
-
- Both systems have been demonstrated as feasible/workable/makeable, but I'm not
- sure what the current political funding headaches are. It's more a matter of
- money & politics rather than technology which is holding up full-scale
- production and deployment of both systems.
- I have talked to Ehud, and lived.
